Returns either the Dodson and Tobler coordinates for the original thirteen pumps, appended with name of nearest road or the fourteen pumps included in the second version of Snow's map in the Vestry report. Note that the location of the fourteenth pump, at Hanover Square, and the "correct" location of the Broad Street pump are approximate.
pumpData(vestry = FALSE, orthogonal = FALSE, multi.core = FALSE)Logical. TRUE uses the 14 pumps from the Vestry report. FALSE uses the 13 in the original map.
Logical. TRUE returns pump "addresses": the coordinates of the orthogonal projection from a pump's location onto the network of roads. FALSE returns pump location coordinates.
Logical or Numeric. TRUE uses parallel::detectCores(). FALSE uses one, single core. With Numeric, you specify the number logical cores (rounds with as.integer()). On Windows, only "multi.core = FALSE" is available.
An R data frame.
This function documents the code that generates pumps, pumps.vestry, ortho.proj.pump and ortho.proj.pump.vestry.
